perf(render): use single Fela renderer

[layershifter]

Fixes #1311.

Problem

Previously we had multiple Fela renderers for LTR and RTL.

Why it is a problem?

• complicated logic of switching
• double usage of memory: each renderer has own cache
• tricks to properly create subscriptions: https://github.com/stardust-ui/react/blob/master/packages/react/src/components/Provider/Provider.tsx#L184

Why we need this previously?

• conditional style transforms with fela-plugin-rtl, were added in 10.2.1
• proper support for RTL in animations - fixed with usage fela-plugin-embedded, required fix for its usage was release in 10.4.1

With latest changes in Fela we can remove this tricks 🚀
